I wonder if this kind of actions would bring or open something like a "precedent" for other situations

It is not the first time that a return of this type has been done, but the media coverage that this particular case has captured the attention of the financial, technological and general bitcoin community.

The worry is that if we allow this now, it might lead to more situations like it in the future. Think about a situation where someone comes with arguments like Craig Wright did againts bitcoin developers, saying that miners should be responsible for users losses or helping them to recover their lost wallets...

Just image that. 

My recommendation to miners would be not to return anything to people/corporations they need learn from their mistakes.

Regards!
