Because history has shown us it is likely game over for what we have enjoyed and rely on now that it's going to Adobe.

It's a good product people really liked, which was acquired by a competitor, and will probably be destroyed by them. Imagine SQLite being acquired (i know it's not a product, imagine) by Oracle. Something you liked and used often is going to become a dumpster fire soon, why wouldn't you talk about it?

I remember when Oracle acquired MySQL.

It's because Figma was just bought by Adobe for a $20,000,000,000.
