People don't generalize. Ads aren't a necessary evil for me; I'm glad to pay a few bucks for a good app without them. And I'd hate to see the whole Internet go that way! I've been reading about the recent crusade of PageFair against ad-blocking, white knights (who somehow manage to profit from this themselves!) on the side of a "free Internet", by which they mean an ad-funded Internet. This is crap. You have a right to charge me to use your site (or app) if you want, but not to force me to view ads. They're a corruption of the whole concept of the Internet. (Not to mention that I have never, ever, bought anything because of an online ad -- more the reverse.)
Shuttle looks decent, much like the BlackPlayer I just checked out, which also has no ads. But I really want something much simpler. No album art, lyrics, automatic this and that. Just a utility to list and play mp3s that I put on my phone.
Where is the stock Android 2.x app that did this? On Playstore I only see a couple of versions put there by jerks who want to profit from ads they've stuck into code they didn't even write themselves. (This is the kind of mentality you get now...)
