Yeah - I get this but when things are free, I no longer assume they'll stick around and I no longer hold it against the business closing the free service down. I think in the mid 2000s a lot of people saw free as a quick way to do land grabs or experiments and google especially. As a result there is this mis-conception of trust. To me it was growing up with the internet and learning that a business needs $$ to operate so anyone selling something for free that didn't have a clear monetization strategy was to be avoided. Sure study it and learn but never trust it for your own well being... my two cents
