Wow, I step away for a few months and a bunch of things happen.
I get both sides, but I think it's positive for a number of reasons.
Obviously it sucks to lose a very nice, very useful piece of free software. Like, I don't use APs, but I would likely compare it to something like OggDude's FFG Star Wars character creator: given no other alternative, having that character generator was fantastic for simple organizational stuff in a game I love. So if that were to suddenly disappear from the web, it'd be frustrating as all hell, since I'd have to manually do all the work and organization on my own.
(Off-topic: God, I'd pay so much money for FFG SW software support. I hope Edge Studios manages to pull off the impossible and works something out with Disney/LucasFilm.)
On the other hand, I think there are a number of positives here. While it does cost money, I do remember one of your (
@Retreater ) critiques of playing Foundry was relying on fans to keep up modules and the possibility of having something no longer updated. It's something I myself said was unlikely in the case of rules, but for smaller modules was more of a possibility, and here we were confronted with it. But Paizo taking up the content themselves means it's much more likely to keep support going than an unpaid fan developer.
Along with that, the official developer getting into the game arguably helps with regard to exclusive official content. PDF import can do a lot, but it won't put in sounds and music, which it looks like Paizo is going to do, which is cool since Foundry has a bunch of unique things it does for sounds. Similarly, I'm not sure how much the PDF transfer can get for lighting, particularly unique lighting effects to create ambience.
More than that, I really hope this means more official support. It would be nice to see them help out on the rules side, maybe helping out with adding effects and such to spells and other things. The PF2 rules are already among the best-implemented and supported out there, but it's nice to see the company going to where it's fans are and putting real support out there. And with Paizo doing this, hopefully it'll inspire more companies to move in? Foundry is getting bigger and bigger and I think this is just great news for the VTT space to have something that is a bit more complex for the hobbyist compared to Roll20 (as well as not needing a subscription).
