Well... most articles are written about one pitcher at a time, and no one is writing an article on Dallas Braden or JA Happ. Furthermore, only pitchers that use their changeup frequently are going to get an article written about it... no one cares if Joe Schmo is tipping his changeup that he only throws once per game... so there is going to be a disproportionately low number of articles on individual pitchers, to begin with. Not sure how many more you are looking for.

Zack Wheeler AND Drew Storen tip pitches with differing deliveries: http://www.nationalsarmrace.com/?p=7080

I think we can agree Clayton Kershaw is pretty good at pitching, and this is even a noteworthy concern for him:

but he has to work on keeping the same arm speed he uses to throw his fastball; he has to do a better job of selling the pitch

It's a conscious action, on every pitch, to increase your arm speed on an offspeed pitch, to disguise the pitch. It's not an automatic thing.

This article is on a unrelated topic, but David Ortiz gives a relevant quote which should give you an idea that it happens fairly often: http://m.mlb.com/news/article/4597054/

Quote:

Sometimes there's guys tipping their pitches out there, and I still won't hit it because I can't focus on that.

David Price used to tip his changeup, he just recently increased his changeup velocity to correct it: http://www.fangraphs.com/blogs/anato...-hit-disaster/
But then he relapsed: http://www.si.com/mlb/2015/10/24/roy...clinch-pennant

Both confirmed it: Price tipped his changeup—maybe not 100% of the time, but enough for Kansas City to buy in.

Not tipping his pitches was Greg Maddux main key to success

Also see this quote about Marco Estrada:

Quote:

On average, Estrada drops nearly 11 mph off his four-seam fastball with every changeup, giving him the largest difference of any right-handed starter in baseball.

A lot of this is inference. We know that pitcher Y is successful because of X, and we know a lot of pitchers are not successful. Therefore, does it not hold highly probable that X is not true for a lot of pitchers?

Somewhere between the 8 or so links I've shared, I think it's safe to say that if a pitcher is highly successful, it is usually because they have eradicated any and all indicators for their pitches.
For the rest of the pack, 100% autonomy just doesn't exist.
