For me it was the license change/redaction. Not because of the new terms (which I agreed with) , but the hundereds and thousands of edit I had done prior to the redaction were lost due to being on the back of data laid down by people who didn’t accept the new license. It was a gut-busting blow to see so many long hours of work go down the drain, and I was not prepared to do it all again, just in case we have the same thing happen again.

I know I am not alone in this.

It's a pity that thread has been disrupted by a troll.

I don't think he understands the OSM concept at all.

I run a geocaching listing site myself, based in Australia, and we have OSM as a map type (admittedly we use GMaps as the primary one). We still have a fair few users using the OSM layer though.

Kind of funny to see all my mapping data on my main rivals website :-)
