As someone else mentioned, it's a non-profit, so I guess it's not technically possible to get acquired.

But I personally believe that the people behind LetsEncrypt genuinely care about the mission and will never sell out for their personal benefit.

If there was a list of organizations that bring the most impactful things to tech per each dollar received in donations and per each employee, ISRG will be up there at the top.
