Nonetheless, .org is for not-for-profit associations, while .com is for-profit corporations. .net is for networks, and .biz for businesses.

A lot of startups use .io, but unless they're located in or are addressing the British Indian Ocean Territory, they should not.

I choose my "providers" taking into account the tld classification. For example, my open source free software projects are hosted on framagit.ORG, not on github.COM. (Well, ok, since people are dumb and they all go to github, I also have clones there, but I expect the commercial github entity to shutdown that service and erase them at any time for any reason their shareholders may have).
