a bit off-topic, it's funny you use all this fancy technology behind the scenes and your iOS app is buggy, slow and always problems with login and notifications which do not update.
I came here to write the same thing, so have an upvote. Tinder’s iOS app is such a gigantic travesty of engineering that I’m honestly surprised to hear they have an actual engineering team.
It doesn't seem off topic to me: it is reasonable to mention the end to end experience and value of particular work. The OP seems to be saying "the company might have gotten more value from investing in a different area than what is in the linked article"
