I don't have a statistical survey, but I have anecdotal evidence of paid services going away, increasing in price dramatically, or remaining the same. Same with free services. I can't honestly say that the paid-for services I use are more likely to remain available than my non-paid services. The key factor appears to be a viable business model, but that's impossible to evaluate from the outside (and sometimes from the inside).
