Except the 2005's Microsoft would still support all their current and legacy products and services as they still do today(heck, I can run the binaries I built back in school in 2001 on my current Windows 10 setup) while Google abandons them in their bottomless graveyard as soon as the paint dries and moves on to the next shiny thing.
Google is not becoming the new Microsoft but the new Intel/Boeing; no need to rectify anything as long as that sweet ad money keeps coming in.
Google is like politicians and infrastructure: they love cutting ribbons and announcing new things but nobody likes maintaining existing stuff as it gets you no fame.
