The title of the article is kind of technically correct but still misleading.

It is true that The Ocean Cleanup "we're going to trawl the ocean for plastic" approach isn't working terribly well.

But they did pivot to stopping trash from washing out of rivers and into the ocean which is working. Stopping the mess from growing is also a very good thing.

This seems like some combination of the enemy of good is perfect and also sour grapes that someone else is doing the thing.

Read again? Negative is the enemy of good, and this project was a net negative. As PR it went well, if you didn't examine it too closely. It was a misnomer from the start - it was 'harbor cleanup' or 'river cleanup' really. Where the big obvious plastic objects are. I don't believe they proposed any method for actually cleaning up the 'garbage patch' which consists of pepper-sized particles of plastic that requires a sieve to see. And which has been colonized by many marine creatures, so 'cleaning it up' would have the side effect of mass sterilization.

Issues are hard. PR is easy, especially if you hand-wave over the hard stuff.
