Considering the market penetration of Google Photos and the lack of any compelling reason to switch, I doubt that grandfathering would have accomplished what they're trying to do here. Phone companies also eventually kick people off of grandfathered plans, or change them so substantially that they are no longer recognizable. For example, I remember the AT&T unlimited plan that came in the early days of the iPhone. It started out reasonably cheap but eventually became extremely expensive.
