It is less bad because it is opt out (and the submission says 'can use', not 'will'); I won't say it's best. From the summary of the changes:

Section 2.K. Advertising and Endorsements on LinkedIn: We added this section to explain that LinkedIn may use you profile picture and name in social advertising shown to your network on LinkedIn. We also explain that social advertising will contain information from you and your connections’ interaction with the LinkedIn site (such as when you recommend a product or service on a company page, follow a company, etc.). We also point you to the Setting where you can control the use of your profile information in LinkedIn’s social advertising.

For me it was not -- I had to opt out. I'm not sure why there is inconsistency, but there are definitely some people who were opted in without asking.

Same here. And I haven't touched my linkedin settings in a very long while.

This is also opt-in for me - flagging as inaccurate.
