I would call pasting-the-URL-into-Google-Search less of a intentional workaround and more of a trick to take advantage of the websites' compliance with Google rules.
Not every HN reader would know to do that, or look in the comments for that "workaround."
That's right, so it's ok for people to ask and share how to read an article in the comments. There shouldn't need to be more than one or two comments about this, and it helps everyone focus on the content.
What's off-topic is the generic tangent of paywall complaining.
edit: The auto-generated bypass instructions will get the top-sorted/top-comment favoritism that we normally try to avoid from users.
If sites don't want people to bypass paywalls, then they would not allow "special" ways to bypass paywalls. The fact that some paywalls have special referrer bypass rules reeks of financially motivated favoritism and entrenched interests preventing competition; the next search engine startup to be created is going to have a rough time of it.
