I do not feel the urge to enact revenge on google or apple. Apple lost me as the customer years ago, and google is losing me as we speak. That alone is painful enough for them. I’m convinced, that if they won’t change, they will die naturally.
Any effort to fight or sabotage them is, in my opinion, misdirected. Perhaps the only exceptions are the lobbying affairs. Those should be monitored and countered. One could support FSF, EFF or other such organization for that very purpose.
