A lot of people in the comments recommend getting a personal domain, but doesn't that just move the single point of failure to the registrar? For example, quoting NameCheap's TOS: "In the event of termination [..], You agree [..] that Namecheap may take control of any domain name associated with the terminated Services." (https://www.namecheap.com/legal/universal/universal-tos.aspx)

A single company can still wipe your online identity. Is there any solution for that? Maybe getting a domain directly from ICANN somehow?

Just use joker.com or other registrars with sane terms of service. Namecheap (together with GoDaddy et al.) is really close to the bottom of the barrel, and should not be used as a representative example of what good registrar should look like.

You can purchase from a NIC for the TLD, but it's pretty difficult and you would likely still be at the whim of their TOS. It's arguably better to switch to a domain name provider as you can more easily get an SLA that makes termination difficult, and in any case switching to a reputable registrar means your domain getting "unjustly" terminated would be much less likely.
