(For me) it&#x27;s mostly a transparency and trust issue. People widely suspected that it was Mozilla looking for another revenue source, they aggressively denied that money is involved. And now it turns out that there potentially is, but no details are published.<p>I actually think that with the way they did the integration, they probably <i>should</i> have received money (Otherwise, why not do a generic &quot;read later&quot; button and a way for services to register instead of adding a single, proprietary service). But for me, right now, the most important reason to use Firefox is trust in Mozilla, so I don&#x27;t like it if it looks like they are not telling the entire story.  (Compare to the advertising tiles: they clearly showed that they are receiving money for it, they also described what they did to preserve user privacy and security.)
