No, HackerOne gets paid by the companies, so they're heavily incentivized to work for their benefit.

I've had three really bad experiences with unskilled H1 triagers that the next vuln I find from a company that uses H1 will go instantly public. I'm never going to spend that much effort again, to get a triager that would actually bother to triage.

except there you spend several months walking an underpaid person in india who can barely use a shell though reproduction steps, get a confirm after all that work and the vendor still ignores you

HackerOne, BugCrowd, et al don't appear to make any serious effort to vet reports themselves.
