If Elon can get enough publishers on board I'd gladly pay more than $8/mo. Maybe offer a tiered system. Or better yet, choose-your-own.

$8/mo: Choose 2

$12/mo: Choose 4

$15/mo: Choose 6

etc.

Then people vote with their dollars which sources are important to them.

Simplicity would be challenging. It wouldn't work if it devolves into something resembling tiered Cable TV packages.
