I don't know what you mean by saying "you are locked in for that system".
Did you expect to get the PS5 version as bonus?
If you have several systems, you always have to buy the games for all systems. It never has been different. You don't get a Nintendo version in addition when you buy Sega.
The system requirements on the GOG store page say that you need a Windows PC, so that's what's required to play.
It would require an authehtication mechanism across all systems if buying one version should entitle you to play all games versions and that doesn't exist.
There is one exception: If you buy from the XBox Live Store, you get the PC version and the XBox versions for games that were ported to both.
