One of the big appeals of Foundry at the time I paid up (at which time there was none of this nonsense I could find anyway) is a pay-once non-subscription model that I can self host. I own the assets in my game world just as much as I own my three ring binder of notes.

After playing both in person and online, I think I like online play a bit better. Theater of the mind is great, but I do like a good tactical game and I find in-person tactical battles really cumbersome. (And I do mix the two anyway, no one expects to actually move tokens 10ft at a time along a river bank). I don't have a big collection of minis, monsters, terrain, etc and while we can all play pretend, seeing a skeleton and where it's looking is objectively more pleasant than staring at a spare d4 and remembering that the 124 side is it's front. No arguing and butthurt players when they think their Fireball or Anti-Magic Shell should reach when I can just plunk down a template that shows it doesn't.

Also a lot of conveniences to be had running your character sheet digitally including never burning through the paper after erasing for the 200th time, easy to transfer items, rules cross reference, etc. Dice are out on display (when you want them), nothing falling on the floor, no passing around dice trays or towers.

I guess I'm just salty I put down my money to a formerly non-political company only to get a dick shoved in my face.
