Burning bridges with the founders is usually more than just not working with them again in the future. Everyone has their own network, and the founders may be good friends with other potential employers, potential co-founders, etc. with the OP.
And if this dispute spills out into public -- "I want to protect the identity of my former employer for the time being" -- then everyone is usually tainted by the end of it. Once it's public, the founders will probably try to justify their decision (by smearing the OP, more or less politely and more or less truthfully), the OP (angry at being smeared) will say something still more stupid, and it will all be preserved for posterity, regardless.
I have no idea what the OP is entitled to, legally or in-all-fairness. But please think through every step very carefully before (and while) burning bridges.
