I know that csgo players are not that smart, but you could use your logic.
Seems that ur pretty upset about the update, so let me clarify everything for you.
In f2p you will only play with f2p players, since u are prime u dont have to worry about it, just like everyone else.
If you will cheat in f2p until you get to rank 21 so you could get prime for free, obviously 2-3 games max in f2p until you get banned. If you buy prime, max 2-3 games in silver until you get banned (same thing as buying csgo before). Noone will invest 100hours in f2p without cheating so that they could cheat for couple of games in prime.
You want a new operation? What does operation consist of - new maps, new crate and missions (I'm assuming majority of players would prefer new gamemode over missions). In last few months we got new maps, new skins and a new gamemode.
