Here is a link to Wargaming’s official feedback form for the new patch.

I see many people on posts today saying that there is nothing players can do to stop the ridiculous aspects of this patch being pushed through but the original crew 2.0 was dropped because of widespread player backlash as was the “Rubicon” patch years before that. Directly complaining to WG through official channels is the best way to make yourself heard, it has worked before and might well again in this case given the level of backlash we’ve already seen since it was announced.

It might do nothing but it also might mean 1.20.1 goes the way of crew 2.0 and Rubicon, there is no harm in trying.
