I support them, in the sense that they don't particluarly bother me. When a site asks me for money to read an article or to subscribe I tend to just close the browser tab and do something else.

The thing is, most articles are a distraction, a diversion. Something I do instead of the thing I should be doing and as such they are very very low value to me.

If the site maintains a standard level of quality of content where their paywall is worth paying, sure. But I think the vast majority of sites (think your average Medium blog, many 'news' sites, or tabloid sites) don't meet that standard, and are probably terrified of the thought of nobody willingly signing up for their subscriptions.

Patreon-paywalls are becoming increasingly popular, with bits of free content as advertising. It seems like a reasonable way to do business.
