So your criticism of google search is that they don't go far enough in appropriating website content?
I'm not native speaker and can't get what "appropriating" means here. But that wasn't a criticism, that was a sharing of observation that, despite of "the fact" that google search is superior and irreplaceable, this is simply not true at least for one guy like me. Discovering that is very hard, unless some default browser in popular linux distro temporarily forces you to non-default default.
Other services were mentioned only to support "completely" part, which is criticism, but not search-related.
I'm not using it too, but not because of that (and I was unaware of amp before). DDG shows instant wiki, stackoverflow, lyrics previews, while google only does that for wiki. I don't use gmail because of crappy ui, ux and designs. I wouldn't use annoying youtube if dailymotion was not blocked. Translate is only bearable for english. Local maps are way better in navigation/street/company info (probably not true for US/EU).
Summarizing, I clearly see no value in google services for me today and it was surprisingly easy to get rid of it completely.
Edit: and in search regard, ddg/yahoo links lag far less than google's redirects and ddg never presented me "you're a robot, enter captcha to not get to our search service anyway" for hours.
