Again, I don't have an issue with outlawing spider tac. But I do think they've gone to extreme's to try and curb the use of it.
I've talked to 6 former players. 1 of them is a friend of my FIL and a former ML relief pitcher for the Mets and Orioles. He's definitely on the older side, but he confirmed what everyone basically knows, which is that pretty much every pitcher regularly used stuff to get better grips on the ball. He says everyone on the team knew it and not one player remotely cared.
The other guys I know never made it to majors or only played college ball. They're all younger than 32 though, so definitely not old foggies. But they all agree it's extremely common throughout the minors/college. And all of them were completely aware what Spider tac was well before it became a household name recently. I doubt they know much about spin rates and advanced analytical data, but they were keenly aware it produces the best results.
