That should be illegal IMO. You are forced to subscribe after you paid.
I’ve even made it a personal policy to only buy digital only games through steam.

Had the opposite experience after a game stopped working 3 days after purchase due to its update (forced, if memory serves). Valve refused the refund because I played the game for more than 2 hours before it stopped working. Haven't purchased anything from Valve since.
That said, the Steam store page does tell you in advance this will be necessary if you know where to look. I don't buy those games, if I want them I'll eventually grab console versions used.
