Hello,
I know about Let's Encrypt and I believe it's a great idea. But helping
people switch from HTTP to HTTPS is one thing and forcing people to switch is
another.
I believe this decision will affect both users and website owners, at least
for a long period of time because:
- some users (actually a lot of them) don't know the issues with HTTP and
they will believe it's the browsers fault and probably they will switch to
another, proprietary maybe.
- some sites owners don't know about Let's Encrypt and that they can get a
good certificate for free. Choosing a free certificate nowadays is not quite
easy.
- some sites owners don't have the money to buy one or don't care. When users
will start to complain the the website is not displayed correctly those
website owners will tell they visitors to change the browser.
I don't think it's a win situation for anyone, at least not for now.
