Because Google implemented warning in their web browser, and you comply without understanding their reasons?
SSL is most useful for credit cards processing.
SSL makes some sense for e-mails and chat messages, also for authentication.
SSL is useless for static content.
I think Google did that for money, just sold the security story really well. They’re smart people, they can’t possibly be unaware of certificates being useless for majority of the web. Here’s the reasons.
Increases entry barrier, centralizing internet even more. For-profit internet companies have zero issues paying for certificates, it’s part of their business. It raises barrier for ordinary people. Also creates more incentive for placing ads on their web sites to reduce costs. Guess who earns most profits from internet ads?
Also, SSL breaks caching proxies by design. This opens market for technically inferior google AMP. Technically inferior, because proxies are closer to users, 20 years ago most office buildings had a caching proxy like Squid or MS ISA Server.
Also, there’s unintended consequence, users learning to ignore SSL errors and proceed anyway. People processing credit cards usually know what they do, take security seriously and SSL errors there often means what it’s supposed to mean, warns about potential hacks. People implementing SSL just to shut up the google browser don’t need security, they care much less and screw up much more often.
