If you are a highly skilled technologist you will not have any issue finding a new job. If you are greatly bothered by the changes at Twitter and the new ownership it is almost certainly for the best that you leave and do something else. I don't see why someone skilled enough to work at Twitter would desperately hang on working for someone you can't stand to try and get some severance. Life isn't fair and this is the free market, and you are earning Big Buck$, dust off the resume and join a new company. Life is too short to live like that.
