I'd like to see them both run successfully side by side, I like both for different reasons and they do each have their own set of advantages and disadvantages.

My understanding of Protip is that all tipping is done peer to peer on the blockchain. This of course fits perfectly with the idea of Bitcoin since it's decentralized and trustless. Being entirely on-chain does have some disadvantages that make it less than ideal for microtransactions. Extensive use of Protip could pollute the UTXO set with a lot of small transactions and result in people playing larger fees to spend their BTC, it also makes it difficult to send someone a tip smaller than the "dust limit".

Changetip is great for aggregating microtransactions off-chain, minimizing fees and potential UTXO bloat. Of course it comes with all the potential disadvantages of relying on a trusted third-party, something Protip avoids.

Since I personally trust my coins a lot more in my own wallet than in any wallet run by a third-party (with the possible exception of a GreenAddress 2of2), I would use Changetip for smaller tipping transactions like you usually see on Reddit and I'd use Protip for larger transactions like donating to an opensource project I want to support.

I'd like to see both of them are existing in the market, competing with each other, and perfecting their service. Then we, as a cunstomer, would choose the best service to cater for our needs in different situations.

This does seem like the best situation. Competition! I'm not into social medias so I don't have a vested interest here, nevertheless I can certainly see the value in the OP's claim about man in the midle and private data vs trustlessness and open-source. I'll be keeping and eye on protip.
