Update strategy
Update strategy

first draft update of strategy.

* add who is tidelift?
* amend sustianability strategy to be more direct about solution
* remove 'profiling' as we're hoping to provide another route for open source maintainers to be paid for their efforts. Of course we aren't going to profiel users like this. And this in no way removes the gratefulness we have for maintainers and their talents. Chapau to each of you.
