No you can't make the exact same argument argument against them.
Subs did decrease when early LFD QoL features were implemented. Saying they would have decreased anyways without QoL requires a magic crystal ball, none to date known to be reliable. Did decrease, and may have decreased anyways are 2 very separate things.
Subs did decrease at a specific moment when certain "features" went into play. Your speculation is just a bunch of "what if's", which is not objective. Your opinion.
