If you use ublock origin, blocking javascript breaks bloomberg's paywall. You can do that for bloomberg.com (and nothing else) by opening the site, clicking the ublock icon, and clicking the bottom at the far bottom right.
Alternatively, using just Firefox: stop (X) the page loading after the content has loaded but before the giant JavaScript bundle has downloaded, and then enter reader mode.
Opening it in a different container (with a right-click) also works.
And with the additional advantage that the site loads faster.
How ironic. Breaking the paywall on a billionaire's newspaper to read an article about a billionaire's paywalled beachfront.
