Revoke my license then Sony, if you can’t then I don’t care about stupid unenforceable clauses in EULAs.
There should never be any sort of EULA needed to access software that isn’t networked. Requiring an agreement to an Acceptable Use Policy is reasonable and violation of those terms resulting in a network ban is reasonable. Otherwise software usage rights should be unlimited and you can prove I caused damage via copyright infringement or prosecute me via CFAA.
It looks like you fixed your issue but I had the same thing happen on windows 10 so I am gonna post how I fixed it in case someone runs across this thread later.
In my case everything had been working previously but after an arbitrary reboot, my windows 10 PC could ping the local network and nothing else suddenly. No access to the tailnet, Internet; DNS or otherwise. On the wired interface that is. I could connect to WiFi and it would work just fine. I had a DHCP reservation set, deleted the reservation, let it get a new IP and then it worked. No idea why? Recreated the reservation and it still worked back on the old IP again
