Is premium support included in all user accounts now?

Do you mean you have to pay for it for each additional user you add if you already have it? If so, Yes.

Yeah I had to get another license saw that line and was hoping it wasn’t true.

Your premium support is typically a percentage of your overall licensing, so each time you add something that causes licensing cost increases, you pay an equivalent mark up on that license.

As far as I know if you add any licence, module or services after your renewal or before your next renewal they will automatically charge you respective percentage for support. It's been always like that
