Paying for "upgrades" to games someone already owns, the decades of "premium" pricing on everything with no sales, their ongoing war against emulators, modders, etc. One big one for me was when my copy of MySims killed the disc drive in my wii, I RMA'd the system and got back a refurb with the note "yeah, you're gonna have to deal with not having any of your Wii Shop Channel stuff on your own, buddy."

Not a policy, but I'm irked by the weirdly cheap build quality as of late, too. I've got NES, GCN, N64 controllers that still work, and every one of my switch sticks drifts with very little use. Plus the rails on the Switch felt cheap, and the audio quality and input lag are bad.
