Interestingly, despite an active Twitter account, he's shown the maturity to not tweet confidential data.
I assume that you make reference here to Lewis tweeting the data about the new wing at Spa? I'd like to add a comment and refer back also to the data sharing which was discussed further back in this thread.
I think the data sharing that goes on at Mercedes is a great idea, if one side of the garage find and advantage, it's shared, benefitting the team. Each driver at Mercedes has a dedicated team of engineers helping 'its' driver get an advantage, to exploit any available data to its drivers advantage. The engineers talk of 'us' and 'them' . There's healthy competition, but the data is shared. It's two way traffic.
The data sharing at McLaren was different. The competition was removed, the 'us' and 'them' was removed and it became an excerise of raising the average performance rather than exploiting the excellent. The engineers were not encouraged to find an edge for 'their man' but rather to follow the lead of the then TP and the agenda he had for McLaren.
It has been documented that Hamilton's data was used extensively to help Button during his low mid season period in 2012. Documented too that the might of the engineering department were likewise engaged in speeding up Button ( at a time when Lewis was getting podiums and still in the championship hunt) and it's great that Lewis was able to help his slower team mate, even if it did distract from the championship challenge. But where was that data sharing at Spa when Lewis was given a two second a lap slower wing and advised that there was little performance difference? Unlike the current state with Rosberg and Hamilton, it wasn't a two way process.
So back to the tweet gate, since that is what I was originally replying to.Yes, Lewis was a little miffed and tweeted the wing differences.........Alonso has used another teams data( spy gate) been involved with having a team mate crash on purpose(crash gate) , blocked a team mate in the pits, asked for team mates to be moved aside......yet this is considered a mature and complete driver?? I think Lewis and Alonso are the best two drivers on the grid, but lets not fall for the 'immature' v 'complete' driver myth.
