I use OVH to operate a small dedicated server, that I use for a very complex home setup(*).
Given that it's a dedicated server, the same one I've been renting for years, and that it's never needed intervention in all the years I've had it, if they raise my prices by anywhere NEAR that amount... I'll find another host.
Sure, I'm not their target market but equally... you aren't gonna penalise me because your other customers want something expensive. I'm not there to subsidise your other customers. New servers, fine. Upgrades, fine. Those people who rent virtual servers and the like where your costs might increase, fine. But people with existing dedicated servers shouldn't be seeing a price hike unless they make changes, or the price of electricity changes.
(*) My external domains are pointed to the dedicated server. That means that they sit on a static, globally-accessible, always-on IP. They use LetsEncrypt to renew, so they're always online and "available". But the actual SITE they are providing is in my house. My home systems VPN up into the server (which avoids all kinds of port-forwarding, NAT, even double-NAT, etc. nightmares) from any of 5G, DSL or fibre connections. The dedicated server then uses Apache to reserve-proxy and load-balance the sites, getting the pages from my home systems via the VPN (with a special "fallback" load balancer which basically serves a page which says "VPN is down" instead of the site when things are disconnected from home).
No ports to open. No dynamic IP worries. No NAT-punching. No changes when my connection fails over. Static locations to access everything even internationally. TLS-wrapped and authenticated at the dedicated server end. Nothing else open or accessible on my home network to make it work.
Given that I host everything from my home TV (tvheadend), Plex, my car GPS tracker (Traccar), etc. on them, it works amazingly well and nothing "external" cares about my internal setup. My GPS tracker just sends the data to my dedicated server and it gets authenticated and proxied all the way back to my home system via secured channels (TLS, VPN, etc.).
