As is usually the case, what they decided was something much narrower than the general case. LinkedIn still can and does make efforts to prevent/restrict automated browsing at scale. What they can't do is selectively block traffic from the plaintiff company altogether, when the content is otherwise publicly available.
> In a November 2022 ruling the Ninth Circuit ruled that hiQ had breached LinkedIn's User Agreement and a settlement agreement was reached between the two parties.
I think you can physically block them, you can't sue them though.
If one scraped the content that's served to a browser when it's navigated to www.reddit.com I would expect that ruling to apply. If the API is considered a separate service, then I would imagine they could restrict access under separate terms.
With the ongoing "slowly breaking old reddit" and the move to SPA and mobile app, the data for comments and posts will be via OAuth API access rather than a server rendered html page.
