If we are getting into the technical definition, bit length, key length, etc. doesn't really pertain to something being encryption or not. By definition a Vigenère or Caesar cipher are consider encryption methods (and Caesar doesn't even use a key) but those are very primitive versions of encryption.

The definition for decrypting something is hazy at best as technically using a dictionary attack against a hash function both "decrypts" it and is loss-less assuming you have any related salts etc (this includes even things like SHA2 because with enough time/resources, admittedly ludicrous amounts, it can be "decrypted" or "de-hashed").

While theoretically true, rainbow tables strongly disagrees :). That is probably the main reason that definition isn't exactly right. I think general definition is actually something encoded so that only allowed persons can read it. It really isn't much of (if at all to most people in the field) a misuse of the term encryption to use it in context to hash functions as long as you qualify that it is a one way encryption method.

You say this as a joke but where I work that's exactly what we use it for. We use it to index and catalog larger records.
It's much easier to check whether a md5sum is unique than to check if an entire record is unique. We obviously can't
reverse it but it is easy to recompute it on a new record to see if it's already in the database. There is the small chance
of collision but as a non-malicious md5sum collision has a lower priority than a life destroying asteroid collision, it's
good enough for our purposes

isn't that basically the way everyone uses a checksum...?
The traditional use of checksum is to verify that a large file or other bits of data are not corrupt.
Using it to compress,index, or deduplicate large files kindof like a "rainbox table" is not usually
what checksums are used for. For one thing it partially goes against what a checksum is
designed for. A checksum is designed to change even on a very minor change so unless you
have very structured data it's very hard to use a checksum to verify if a record already exists.

I use https most of the time, but how does it count to access e-mail, when the e-mail service is provided by a third party so they have access to all my communications.
In the end, there's always a third party involved that may not care about the secrecy of my communications, so end-to-end encrypted, is probably none. I connect to my work computers using VPN but then again, my employer probably have access as of what I'm typing and doing.
Does having partially encrypted communications help? Perhaps. Perhaps, so that Comcast/Verizon/T-Mobile or other carriers cannot steal the ad business from Google, Amazon, etc.
