I for one was unaware that the G+ comments could be and indeed
were being subject to actions where they could be automatically removed/erased from items in your Inbox, without your say-so, as per the manner described in the opening post.
There is a general rule related to the design for privacy and security of personal email - a principle - that one's Inbox
is personal, private, secure, sacrosanct and, for most purposes, inviolable.
Making the point that Yahoo or whatever have been abrogating the principle for years does nothing to ameliorate the action, merely serving to show Yahoo or whatever for what they really are. I had already arrived at the conclusion a long time ago that I wouldn't touch Yahoo with a bargepole.
For me though, this is a new discovery. It is not just that it seems to be yet another of a growing number of reasons that have surfaced for
not using Gmail - and especially G+ - but one with more
weight than many of the other reasons.
Whilst I had also previously arrived at the conclusion that I wouldn't touch G+ with a bargepole, it now seems that I'm definitely going to have to consider leaving Gmail after this. Which is a pity, as, being skeptical I had only slowly started to trust and rely on Google and Gmail in the first place, operating on the maxim
"By their fruits ye shall know them." - Mathew 7:16.
Unfortunately, Google seems to have just undone themselves somewhat, according to the same maxim. There's not a lot you can do to repair a situation where you have once breached someone's trust. It's kinda permanent. If you can do it once, then you can do it again and probably will.
This is more evidence - if any were needed - that "Do no evil." is a just a cynical cliché. But that knowledge is not necessarily a bad thing
per se, because it has at least stripped off any possibly naive trust I might have built up in Google, so that I can see them more objectively as just another mediocre service supplier on a flat grey plain of mediocre service suppliers.
Ah well, "You get what you pay for", I suppose.
