I have seen this in some small providers. Doesn't last long since the 
chance of collision is high. It then becomes a VPN.

I've seen this too. Once again small providers who pretty quickly get 
caught out by collisions.

The difference is that ULA could take years or even decades to catch 
someone out with a collision. By then we'll have a huge mess.
