It can certainly raise questions about popularity, however, as long as you also adequately consider their tendency for rent-seeking, monopolistic behavior, etc.

It can certainly raise questions about popularity, however, as long as you also adequately consider their tendency for rent-seeking, monopolistic behavior, etc. In this specific case it's more that I'm having a hard time picturing serious "cloud"-based web companies that decide "Oh yeah sure we'll just shut our site down if we get too many visitors". That would mean this feature is useful primarily for hobbyists, which are more likely to be put off by (and react like they do to roaming phone charges to) uncapped costs (and also not a reliable source of revenue), weakening the revenue argument for removing the feature.
