Maybe developers should focus on the subset of platforms that they know they can deliver a first rate experience on, instead of forcing support for every platform imaginable.

It's a sad state of affairs for the web when we see articles claiming that one company's failure to adopt a standard amounts to threatening the web. The open web supports and should encourage competition, not blind homogeny.

I don't think it's misguided for a company to hesitate in supporting a platform which will enable its users to jump ship to another competing company.
