I work on a cross-platform App used by millions of of people and one day during event that runs on our App google blacklisted out domain as phishing (for all of chromes) because we had too many dots url in the url and too many requests coming into the service to quickly.
So even IF you DO get past the ban-hammer, there is always another ban-hammer just round the corner if you app gets too much traction.
Google is great until you get caught in the web of censorship.
Apple is great on the surface but a hot-mess of bugs under the hood.
Devs at chrome seem more compentant then the devs who work who on webkit. Both just serve to reinforce parent companies positions. The APIs that the parent companies use, most of the time, the rest of the APIs, its anyones guess when they will break release to release.
