They've published audit results as of June 2024, including of their no logs policy (not familiar with the auditor so no idea if they're reputable or not). And I can't find any evidence of them having outright refused to do an audit - the main issue I see is that they didn't keep their original promises for when it was supposed to be done, because (according to them) they've had a bunch of infrastructure changes over the last couple of years that held everything back. I will say that that lapse and the lack of transparency following it is concerning - there should have been an easily accessible page or an email detailing the reasons for any delays, rather than a bunch scattered Reddit comments and tweets.
I mean, it seems obvious why they would post those - many people immediately write off any VPN-based in those countries without actually evaluating whether there's a realistic threat from such membership, as I was talking about before, and that's a deterrent for potential clients. A business defending themselves against potential loss of business from what they perceive as misinformation is par for the course, I think. The main issue is whether the contents of said posts are valid, and prima facie it seems like most of it is, at least to me - I'd have to see a specific rebuttal to dismiss them based on this.
Also - being nitpicky here - two blog posts across four years doesn't come across as "keep actively publishing" to me.
That might be the case - I don't really use it for that so wouldn't know. What I can say is that interestingly, their dedicated video streaming servers seem to be better at dodging VPN detection than the normal servers - I've had them work for sites that block access from VPNs, though not consistently. Probably just that the IP ranges hadn't ended up on any blacklists at the time.
