It’s not even necessarily the ISPs that are doing it. In many cases they don’t like this because their users start getting blocked on websites; it’s bad actors piggy-packing on legitimate users connections without those users’ knowledge.
There are residential IP providers that provide services to scrapers, etc. that involves them having thousands of IPs available from the same IP ranges as real users. They route traffic through these IPs via malware, hacked routers, “free” VPN clients, etc. If you block the IP range for one of these addresses you’ll also block real users.
It’s not soaring demand but cratering supply that’s spiking prices. Millions of chickens were culled due to bird flu and so there’s an egg shortage.
Just going to mention that if you’re okay with non-FOSS office software, I really like Softmaker’s suite (their buy-once non-subscription version).
You will be if you call customer support and get an AI that can’t help.
