Hetzner have definitely always been scumbags about the bait & switch on aspects of their service like that. Granted it's pretty typical of the too good to be true rule of life.
I have only had and have heard of great experiences with Hetzner. For both their offerings snd their support. I am based in Europe though.
I can't think of a single other instance of bait and switch with Hetzner and we run a fair bit of infra with them.
Been using them happily for a few years. They’ve been rock solid and cheap. Can’t complain, even about this hike.
Do you have any details? I was about to move all my services off from vultr to hetzner due to the much better pricing
