It may be that there are many projects relying on Stainless, or, as a sibling comment points out, it may be portfolio-based stack selection rather than actual feature dependence.

Either way, it does seem irresponsible and tone deaf for an acquiring/hiring company and an acquired/hired company to send these conflicting signals. If one puts oneself out there as dependable in the face hopes and needs of other, smaller, up-and-coming projects, then a rapid wind-down for $ is incongruent with such a posture.

So much so that, at least for my part, I'd be quite reluctant to hire someone who had engaged in this sort of bob-and-weave pursuit.
