Permissive license is basically for you and contributors to provide free labour and when mature enough, big corp X can just exploit it and use it for their own benefit off your free labour if needed.

There are actual good and big projects that use permissive licensing that have not been overtaken (postgres for example) but they mostly have very strong, cohesive business and market plan to achieve that, plus the bature of their software.

If your software is actually complicated and useful, don’t let corporations exploit it for nothing.

Keep your project healthy and alive by using LGPL or some similar FLOSS license instead of MIT. MIT and other permissive licenses are horrible.
