For example, I would use email address A for company A, B for company B and so forth. If company A ever gets hacked, I can just block any emails going to email A and not worry about playing whack-a-mole with the 100s of email addresses that spammers will use.
I can also use the email addresses as a way to auto filter or apply inbox rules.
I'm very surprised users only use 1 email address at a time especially if your email gets leaked once to spammers, you have to start dealing of spam or hoping your email solution has very very good anti-spam measures.
For me, this is just a normal usage of an email client.
In Thunderbird, I can directly edit the "From" field to whatever value I want when I send the email.
I can make it a random value such as "[email protected]" and it will happily try to send it. The email address can also be from a domain I don't even own.
From the Gmail, docs, I have to manually go to settings, enroll the additional email address, then manually have to select the "From" address from the dropdown menu. I cannot put an arbitrary email address (including arbitrary domain). This will have to be done each time I want to have a different from header which means if I want to have a randomly generated email used as the "From" address for every one of my emails, it's not going to be easy in the Gmail interface.

Wrapping a HEVC file in a container does not automatically void any patents of the contained file. Otherwise, anyone can shove any patent encumbered file format in a ".zip" container (or any container/wrapper) and avoid any patent or licensing issues.
