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.
