Games run a subset of network connections: Consumer Homelines.

They don't run in corporate networks, over public wifi or over mobile networks, all three frequently block non-standard ports (my city's free wifi blocks everything except 80 and 443, DNS is hijacked).

These three network types are also important, maybe more important than simple home landlines since they affect the people paying shitloads of cash or represent a very significant marketshare.

Besides public wlan this isn't an issue. In corporate networks it may be company policy to use their resolvers. External resolvers might not work for internal names, so their use is probably limited in the first place.

Mobile networks should allow all ports, if not call your regulator.

So 1 out of your 3 are actually important. Also, firewall rules can be changed.

I'll give you corporate networks though that's more guesswork than actual hard data on that. Plus point still stands that other protocols will be blocked unless using 443 or 80 ports.

Mobile networks in my experience block a variety of protocols and intercept DNS fairly regularly, even in presence of DNSSEC or DNSCrypt. Not sure what calling the regulator would give me, they're not responsible for what ports the network blocks. Not every operator is in the US, a majority of people do not live in the US and may want to use the internet without the operator playing around in DNS responses.

Yes. But this is a corporate network. It's not up to you to decide which protocols should be allowed or not. (Unless you are in the position to do so of course) I know it's quite easy to tunnel everything through something, but why do that in a corporate environment. If you need to access X then get access to it (via proper channels?)

But do they block port 853 and if so, on what grounds? They sell you an Internet access, if a port is blocked, this is no longer a valid Internet access. If the port is not blocked however, then the ISP can no longer play around in DNS responses.
