I don't really know what ads they showed, as I used an ad-blocker. I'd believe that it's probably annoying, but the same is true of most websites that show ads. Reddit Gold provided a commercial ad-free option, so it wasn't a requirement even without blocked ads. And unlike most companies, it was possible to purchase Reddit Gold without linking to one's financial data, since they provided purchase options bounced through cryptocurrency and such. As web services go, I suppose it was probably a fair bit better than the average.

I'd have probably been willing to buy commercial Reddit service -- I mean, I've subscribed to Usenet service, have commercial email hosting service, have commercial VPS service. I don't have a problem with commercial service, as long as it's something solid. The value-for-money was probably pretty good, given how much I used it. I just don't want to be obliged to run their binary code on my systems and have data extracted from my system and be data-mined other than what they get from my web browser or open-source client.
