They are splitting the current Google Wallet app into two different apps; Android Pay, and the New Google Wallet. Google's blurb on this states that they are splitting it into "two simpler apps", which, while correct for the individual apps, actually makes using the functionality more complicated, because you have to remember which app can do which kinds of transactions. They also have a FAQ that answers all of the questions that their pow-wow thought might be frequently asked (Lets not kid ourselves, we all know that these lists are actually MBFAQs), but they did not include the one I wanted to ask: Why are they doing this?
I think I might have the answer to this, and it is a universal one from Google. As a frequently frustrated user of many other Google services, having asked dozens of questions about why seemingly nonsensical changes have been made to various services, and never having received a reasonable answer for a single one of them, Google's universal answer to the question "Why?" is simply, "Fuck You. That's why."
I have been slowly transferring my data off of other Google services for the last 6 months. I used Google Wallet just today before reading about this new idiocy. I'm probably going to miss this phone swipe ability, but I'm not changing to the new app. I am tired of the Google culture of disposability. There have been too many things that they made, and that I enjoyed, and that they then trashed. What they need to realize is that not offering any explanation for things like this makes me as a customer feel trashed. Bye Google. You finally broke this camel's back.
