Fragmentation and the frequency of device- or vendor-specific bugs and other issues take a lot of the fun out of Android dev for me.

Unless you're Facebook which has recently been caught abusing silent notifications to start up in the background and continue running permanently by streaming music at zero-volume while draining battery.

Apple responds decently when developers have big media presence notice their abusive process and rolls over passively when powerful players like Facebook have them over a barrel. It's a stormy ocean when you're independent. Best to be careful.

increasingly disinterested in

You mean 'uninterested,' not 'disinterested.'

Uninterested may have been better, but disinterested works fine - see the usage notes (desktop only for some reason): http://dictionary.reference.com/browse/disinterested

It's a matter of philosophy. In any case, the common usage will always win. People don't consult the OED when talking, or even writing blogs. So language changes.

Did you know that even the OED now includes the awful non-literal meaning of "literally"? Oh the horror ...

Don't do anything that is likely to cause significant harm to them. Examples of this include: (a) negative press publicity e.g. porn app, drone strike app, (b) stealing from or harming their customers and of course (c) this app where they will have to cover the cost of you putting heavy objects on something that it was never designed to do.

If you want to damage your own phone go ahead. You can build a weighing app and deploy it to your phone. But expecting Apple to endorse (which is what the App Store actually is) stupid behaviour was never going to happen.
