Read all the updates of the last couple of days, learned lots from many wiser than me, and understand the various viewpoints. Each has to be persuaded for themselves, for sure.
For me, it boils down to: Legacy looks like a great body and I would guarantee to buy it if their business practices were like Maitreya. But they're not, so I won't. The whole shopping experience at their sim is awful; and the amount of concrete information on their website is abysmal - just a few very random FAQs and a whole ton of hype. Compare this to Maitreya's informative blog. So that's my approach, good for me and apparently quite a few others. But I do understand why some take a different view, and they are entitled to it.
By the way, as to SL disappearing - hey, true - nothing lasts forever. The Roman Empire gave it a good go, the US (aka American Empire, especially if you're from the South, hehe) is making a fair attempt but I think are past their pinnacle, and the same is probably true of the Linden Empire. Sansar seems to be going nowhere fast. I wonder what is around the corner?
