(wondering what OSS projects he's talking about there)

According to his GH bio, he's part of the Ortus team... Can't say as I've heard of him or any of his OSS projects but I do sympathize with his frustrations... Even Macromedia volume licensing was a bit of a black art and it's only gotten more so under Adobe (and I know even Mark Takata is frustrated by it -- I won't @ him since he's on a well-earned vacation). I will say that Lucee isn't really any better as far as the "big picture" is concerned. They've also been resolutely deaf to pleas to fix certain bugs, they're pretty terrible about documentation (there used to be an argument that "we're CF-compatible so you should consult the CF docs"), and they also introduce regressions and break widely-used software from time-to-time. They are "better" on pricing simply because they're free but the sort of companies that have enterprise support licenses with Adobe aren't going to switch to Lucee without similar support contracts in place and I don't think the Lucee org can realistically offer that... And I will say that $2,500 per year in support is peanuts. We were using a proprietary search engine for a while (on-premise) and licensing/support for that was $6k per month.

As for some of the claims in his blog post, Adobe has addressed similar comments here in the past (e.g., about new customers buying CF), and when devs from small-ish companies have echoed some of those complaints, Mark T has been quick to want to reach out to discuss specifics to address any real, rather than just perceived, issues.
