This is an increasing problem and I too think that larger providers try to get control over mail infrastructure. GMail isn't really a solution for professional correspondence in my opinion. I am surprised so many are oblivious to that. Other private mail providers didn't keep up with SPIF, DMAC rules/configuration and large providers like Microsoft and Google might blacklist them outright. Leaving mail infrastructure for shitty tech companies is a larger problem than some spam in my opinion as there are powerful solutions available already.
