I think you're being unrealistic, if you expect popular apps to quickly appear on Sailfish phones. If you have an app running on Android and iOS, you're already supporting the vast majority of modern mobile phones. If you want to cover the market more completely, Windows 8 would be a sensible next platform to support. The next logical choice would be Blackberry. Even Tizen would appear on the list before Sailfish, since Tizen is backed by very rich companies. You will have the choice of not installing Android apps, and by supporting Android there's a chance Jolla will be successful enough to keep providing you that choice in the future.
