for domains I'm actively using, I use Route53. For domains I'm not actively using, I don't mind name.com is parking.

I didn't mind name.com parking my domains either.

I do mind the idea of them treating ever possible 3LD as a parked domain, when my domain is not parked (and configured using their Name Servers).

For anyone who doesn't want to park inactive domains, you can just remove a domain's nameservers, and users will just get a DNS error. (NXDOMAIN)
