I'm seeing a number of posts about folk thinking of leaving #AndroidDev due to Googles policy changes.
For clarity I left the #Android world this year, and largely for those reasons.
I bought a T-Mobile G1 on the first day. I've built SDKs and firmware for Android, I have commits in the AOSP. I built (and sold) an app store in the early days. I also worked on the Android team at Google for a while.
Android, to me, is now a Google product. Not the open platform it was.
My advice; Just do it.
