I agree, wholeheartedly.
The increase of Premium fee is perfectly fine, and honestly, I was expecting this to happen long ago.
The increase of cashout fee is completely unfair though. If Second Life has an economy, it's also because content creators spend time and effort to create beautiful content that keeps LL customers operational in their platform.
Many people are making a living off SL, and it's not the right decision to simply remove a chunk of their earned profit.
I have seen benefits being mentioned, but, what is their beneficial extent? We have new Linden Homes, yet their number is limited, and most of Premium Subscribers still are waiting for one, Animesh in their current state, are excessively primy objects, more groups isn't a big deal at the moment.
People (yes, we are real people) like Janire are the reason why this fee increase is completely not justified. Janire has been using her SL income to help others in RL, to ensure stray animals would find a home, and now, part of this might not be possible anymore, for some hard-to-explain reason.
