This statement to me seems to have no basis in reality and no supporting examples. The EFF is a non-profit whose interests often directly clash with that of telecoms, particularly when it comes to advocacy of online privacy vis-a-vis E2E encryption and general anti-tracking lobbying and awareness initiatives.

Their general stance against telecom-enabled broad government surveillance also indirectly harms telecom bottom lines. I could go on, really.

I am genuinely curious if you can provide clear counterexamples which appear motivated by alignment to telecom interests though.
