I don’t think that follows. Most users of a translation app don’t have any ability to judge the quality of the translations it produces, so the only distinguishing feature is ubiquity - if every language you can think of is in Google Translate, you might never go looking for other apps. Plus if you want to keep the best linguists employed, you have to give them fun things to do. Hard to write papers making Spanish translations a fraction of a percent better.
