Standard note: I'm not a lawyer...

You were making the point of choosing a legitimate company vs a shady company, as a way to mitigate risk. Which is a good idea. But it's also worth noting that -- especially in the tech industry -- a good company one day can be bought by a shady company the next. (Although I'm not saying Oracle is shady, I didn't stick around long enough to find out.)

Also, if a company doesn't purchase all assets and liabilities (happened to one company I know of last month), and instead acquires pieces, then it may not be a straightforward change of employer.
