A bad experience with an entity is a legitimate reason to form a bias against them; indeed, that's the point. The nature of the threat that Google poses is likely to leak into many activities inviting criticism.
and who has been locked out on holidays multiple time in the last 2 years with similar effect, only that an SMS would not reach me...
these are not the only shitty things in my existence brought by google.
perhaps then, the author is entitled to have a grudge for another reason.
futhermore:
if grudges are so bad, then the opposite: what of endless cheerleading for the status quo - are motives there also questionable?
