Although this operator was historically useful, it has become less and less useful for SEOs and webmasters over time. On top of that, Google has said to webmasters on a number of occasions that they should be using the Google Search Console link report for better link discovery because the link operator only shows a “sample” of a site’s links.
It was noticed last week by Bill Hartzer that the link operator stopped functioning for a number of large sites, including [link:www.google.com]. But, it did/does work for other large sites, like [link:www.yahoo.com].
Gary Illyes, a Google Webmaster Trends Analyst, told everybody on Twitter that the link operator wasn’t removed:
@webrankinfo the short answer is “no”. For the long answer please email [email protected] @Missiz_Z @JohnMu @bhartzer

Check out the following screen shot that shows it not working for a link command on google.com:
Here is what it looks like when a link command works (in this case, for yahoo.com):
At this point, it seems that Google has no more to say on the matter, above what Gary Illyes already said on Twitter.
