Your actual address is included as a CC, so people can directly reply
to you, and probably are automatically doing so without even noticing.

As a link further down the chain responded, it's due to part of spam
busting.  Your emails (mine, and others) going through the list server
get changed in a way that triggers some servers anti-spam handling. 
Rewriting the email to have come from the list server, instead,
sidesteps that.

a) It will depend on what you send from.  

If your own mail server says that only *it* is authorised to send your
mail (mail "from" you), then *everything* else is unauthorised.  That
is the norm, these days, and generally a good thing.  It can stop
spammers fraudulently using your from address.  Amongst various bits of
instructions that can be applied to your DNS records, SPF has two basic
options regarding such unauthorised mail:  It can tell recipients of it
to treat it with suspicion (flag it, but pass it through).  Or it can
say that unauthorised mail should be a hard fail (e.g. destroy it).

b) It will depend on what receives it.

Each server that receives a message *can* check various DNS records,
and other email headers, looking for info that validates or invalidates
your mail.  They *can* take action, such as:  Refuse to accept it (and
the sender will get a error).  Let it through and flag it is a
potential spam, and let you decide what to do with it.  Let it in and
quarantine it (making you have to specially log into them to check for
quarantined mail, and without any notification to you that you needed
to do that).  They could spam folder it, and it may appear in a folder
that you can easily check when doing your mail (if you were doing
webmail or IMAP).  They can destroy it on site (with or without any
notification to senders or recipients.  They *can* do nothing at all.

Because there's a lot of a mail server *may* do this, and fewer of the
server definitely *will* do this, managing it this is not very
straightforward.

A list server may have to deal with a lot of errors from Yahoo and
Gmail (amongst others) not wanting to accept list mail that the list
has adjusted in some way (adding addresses in headers, adding footers
to message bodies), and a list's admins may decide that the simplest
solution is to rewrite the messages so they're from itself.

I'm quite okay with that, I don't want private replies, and private
replies aren't much use to other people studying the same problem on a
list.

Though it might be an advantage if the list set the FROM address with
the poster's name and the list's email address, rather than my reply to
Todd automatically being addressed to "Community support for Fedora
users" and not grab his attention in his list of emails.
