Unfortunately IBM is going to ruin everything that was good about working for Hashicorp and eventually everything that was good about Hashicorp products.
I worked for a company acquired by IBM, and we held hope like you are doing, but it was only a matter of time before the benefit cuts, layoffs, and death of the pre-existing culture.
Your best bet is to quit right after the acquisition and hope they give you a big retention package to stay. These things are pretty common to ease acquisition transitions and the packages can be massive, easily six figures.
Then when the package pays out you can leave for good.
