There is the multiple proprietary formats that they have used to try and have absolute control, such as betamax and blu ray. While betamax thankfully failed, the proprietary DRM bullshit in Blu-ray continues to be a thing.
They continued to make Spiderman movies for the sole purpose of holding onto the license. This eventually led to Disney being unable to use the character without Sony's permission despite Spiderman being a Marvel character.
There is the Vita using a proprietary micro sd card format that prevented you from saving your game unless you paid Sony for a Sony branded micro sd card that they charged you several times the normal price for, despite it just being a basic ass micro sd card. A regular micro sd card will not be recognized without hacking the Vita software, despite the fact is literally just a regular micro SD card slot.
There is the thing with the Bleem emulator software company being bankrupted by Sony after Bleem beat them in court. This was a major blow to the emulator software scene for years after.
They were working with Phillips to develop standards for the then upcoming CD-ROM format. They reportedly pushed for making the cd slightly bigger at the last minute because they knew Phillips was already building up a factory to be able to make CDs at the currently agreed upon size and increasing the size fucked over Phillips completely.
While Microsoft and Nintendo have long since buried the hatchet, for many years, Sony was the main reason that many cross platform games such as Minecraft, could not crossplay with Sony's consoles.
Similarly, Sony and Epic had some issue where logging into Fortnite on the PS4 locked you out of being able to login to Fortnite on the Switch. Sony shrugged their shoulders and gave no explanation until it became such a big deal they had to address it. Meanwhile the Xbox had no such problems with the Switch from the start.
Originally Sony had sold the Vita is being a system that could stream content from the ps3 over 3G data signal. This turned out to be such bullshit they got sued over it by the FTC
They were fined by the EU some years ago for colluding with other companies to fix the price of videotapes and then shredding the evidence and obstructing the investigation into the price fixing
The very thing that led to them creating the Playstation in the first place, was part of their corpo strategy back in the 90s to buy out other companies as much as possible, kind of like how Microsoft is doing now. The deal they had with Nintendo would have given Sony a major foothold in the gaming space while fucking over Nintendo's business, which would have allowed Nintendo to be acquired by them. From my understanding, during the time they were working on the Playstation together, Sony also filed a patent for a cd rom based console that didn't have Nintendo's name anywhere on it that was generic enough they could have sued Nintendo if they ever tried to make a cd console without them. I bet you never hear that part of the "NIntendo betrayed Sony!" story.
Sony currently owns about 95% of the American anime market through subsidiaries (Crunchyroll, aniplex, funimation, rightstuf, etc.). The whole "KickVic" thing was done with approval from them as they were involved in "investigating" the allegations. The reason the American anime market is so shit right now is almost entirely their fault as they are almost all of it.
The PSN went down for weeks like in 2011 after a hack exposed the personal info (including credit cards) of like 100 million people, due to their shit security practices. AFAIK they only ever got a slap on the wrist for this and everyone magically forgot this happened a few months later.
They once updated the firmware on the PS3 just to block people from installing Linux on it.
They were trying, along with Microsoft, to push for an "always online" console for the ps4 and only changed course when they saw how badly the Microsoft E3 press conference was received.
They have been accused of creating artificial scarcity on console launches to drive up demand. Either that or they are really shit at launching consoles with sufficient stock because it seems to happen to them a lot going all the way back to the ps2.
Some people figured out how to break the encryption on the PS3 architecture to install homebrew and published a report on their findings. Sony sued the shit out of them.
Off the top of my head:
The PSP go
The Sony Vaio line of computers shudders
