I picked the only instance I know that actually charges its users an insignificant amount ($20/year), thinking it'd give me some sense of security that it won't just go away one day. I've been paying for it for 3 years in a row without a second thought about it.

Anyways, on Aug 1st their pricing is increasing to $50/year (150% increase!) and now I'm far less convinced that the value it offers is worth the money.
