I don't much about private equity, but Corel is owned by Vector Capital, so maybe they're providing the money? https://www.vectorcapital.com/investments/case-study/corel

Do Vector Capital specialize on Vector Graphics software companies?

Yeah, I would have expected this to go the other way around. “Parallels bought Corel? Corel still exists? Why would Parallels even want them?”

I'm kinda shocked they both exist. Both were good products back in the day, but in 2018? Come on.

What do you base this on? Is it that neither has released a front-end javascript framework or an in-house container orchestration tool as open-source (that I know of)? Or is there some other hipness criterium that they failed to meet?

Nah, I'm old or at least in tech years I'm old. I've worked with projects before containerization I have been a former user of both products. I didn't imagine Corel had the capital to move out of bargain-bins.
