if you indeed own such a small amount, then yes, you vote is as proportionally impactful as your share. I don't see what's wrong.
As for management giving themselves 10x voting rights - that doesn't just happen out of the blue. If a large portion of the shareholders decide that it's the right thing to do (by voting), then yes, it can happen. But i highly doubt that a majority shareholder would vote themselves out of control. It's quite likely that the founder is doing this to retain control despite offering to create more shares. The new buyers of said share knows this, and tacitly agree as indicated by their purchase of said share.
