Google, once the tech enthusiast darling is looking more and more like Microsoft did in the mid 90's.
Now Microsoft is switching to chromium as a browser backend it's no surprise we see Google moving to limit Ad-blockers.
Google really got entrenched with the tech enthusiast crowd because gmail was free, quick and had good spam filtering. Now we are all feeling the consequences of encouraging non-technical people to centralize their emails with them. A once open and vibrant standard is increasingly looking like a mono-culture with both Google and Microsoft's opaque filtering and non-standard blocking making running your own email server almost impossible. Along with the launch of google's AMP for email we see yet another example of Google pushing through their own interests over the interests of the email ecosystem.
