AutoDesk (CAD/BIM/etc) is also getting like this. Maybe not totally Adobe yet, but they too also basically have a lock on their industry. Just like with Adobe, some alternatives exist and a few might be good enough, but AutoDesk bought so many competitors and/or companies that most of the time they are the only game in town.

Bentley (not cars) is another company I loathe, but I've already gotten off topic.

The professional software industry is a cesspool across all industries.
