Very UNWISE.
1. Killing true online status- This requires fixing on LL server side, and by eliminating this feature, now stores using online status boards for their staff aren't allowed to work, and there's still ways to tell even from the stock LL viewer if someone is online or offline. All you've done is listen to a vocal minority whining about privacy "rights"
2. Killing viewer tags, and system information. This eliminates the average person seeing just how few actually use the stock LL viewer, and how many use a third party viewer. It also breaks features used by several TPV's when offering in world support, such as a command that the user has to confirm when trying to get system info to diagnose a fix. That, and people LIKE the ability to change the color of their tags.
3. Seriously? Any features that alter the "common viewer experience"???? That is so poorly worded to include almost anything not in the stock viewer. It already seems temp uploads, widely useful for people creating custom content for others, is under the crosshairs for this one. How long did TPV's have Avatar Physics before LL finally decided to add it?
These policy changes sound more like "We don't like how TPV's are doing a better job than us, so we're going to kick you all in the gonads and cripple everything you like till you all stop making anything that isn't like ours, and you go away"
This seriously hits my anger button.
