Ehm... What?
In what way do you perceive an https-only site to be more restricted, less free, and/or having strings attached?
The only thing I can think of would be if you object to the site saying "you must use this specific protocol (https) to access the site's content", but requiring the https protocol is no different in that respect than requiring the http protocol. Both are widely supported in pretty much any software you might want to use to access the site - you can even get telnet clients with TLS support if you feel requiring the use of a dedicated web browser to be too restrictive.
