RDR2 was on my backlog of games for a while, I started playing 2-3 weeks ago, I upgraded to PlayStation plus extra just to play it. If games can be removed like that from PlayStation plus extra while someone as start playing it and forces you to buy it if you wish to continue your walkthrough. The game is still 79$, I'd say that's a pretty good reason to not renew this subscription.
They should at least let people play if the game was already installed from a plus extra subscription and only block players from re-installing the game if it was previously uninstalled or if we unsubscribe from plus extra. That's a cheap attempt to money grab.
