It's time to unlearn what you have learned in LITS (or should I say TSLI?). For subvert your wildest expectations, this puzzle will. It is an Inverse LITSO!

Rules: Place an unshaded tetromino in every region, and shade the remaining cells. Two tetrominoes of the same shape may not share a bold border, counting rotations and reflections as the same. No 2x2 region may be entirely shaded, and all shaded cells must form one orthogonally connected area.

Notes
- The example is a little bit tougher than usual.
- Don't forget about O tetrominoes! These are implicitly not allowed in LITS by the 2x2 rule, but are fine here.
- Tip: For small regions it may be worthwhile testing all options one by one.
