Google Photos could be the greatest thing ever, but it's too late for that. No thank you, I will pass on adopting Google's latest momentary fancy.
Google can't be trusted as a custodian of users' valuable data. Google has the attention span of a sleep-deprived toddler. In the past, it created amazing products, which I wove into my life. Then Google got bored and dropped those products, replacing them with other products I didn't like as much, again and again.
The incentive to destroy and replace products is baked in to Google's performance management ritual. I'm weary of the resulting churn and refuse to be burned again. In addition, I'm fed up with Google's fixation on low-contrast designs. I'm patiently disentangling myself of all Google dependencies.
