It sure looks like you're trying to make this about some cancel blah blah nonsense, when it's not at all. It's simple: backblaze used a consumer-grade registrar for their ostensibly business domain. That consumer-grade registrar got probably a spurious complaint -- or maybe even a real one! -- and gave backblaze their full $12/year worth of service backblaze paid for.

In contrast, a business-grade registrar won't take domains down for a handful of complaints, and will aggressively work to contact someone inside their customer.
