I agree, and am getting downvoted in other comments for this position. If you sell a small company to a giant one, there's a major risk that they will sunset your work. It's the risk Nate knowingly took on when he sold the company.

No surprises here, no sympathy from me, and his blog post reads like he's a sore loser.

(Disney sucks and isn't blameless, but this is very much a standard business practice.)
