As mentioned, folks are going to play the game the way they see fit.
I used to sneak every so often but now rarely .. and then typically in response to a sneak. I find it excruciatingly dull to fly high or off to the four corners to try and avoid the fight and sneak in a bomb. Granted, the objective is to win the mission, whether it be BTB or BTC, but I find it more exhilarating to eek out a win while sharpening your teeth in the valley of death.
It happened this morning ... spawned in to a BTB where we were outnumbered 6-2. The reds were a mix of low-medium ranks with a high rank. Blues were me and an air marshal, who was accused of dropping. I think this marshal is noted for dropping but I was too busy with the reds to notice.
Anyhoo .. a brigadier snuck over the top and took out a hangar. On the second one I called out "Real impressive ... not". The red high rank seemed to think I was harsh, saying he was only a brigadier. So? He was a brigadier, not some noob fresh off the kiddie servers. He made a couple of attempts down the middle but generally stayed high and out of the fight. I was tied up with reds and noticed he was missing again so I mentioned it will be over soon since the brigadier was sneaking again and we were down to one hangar. I got shot down and spawned and sure enough he was in the final dive and so went the final hangar.
Long winded I know, but for me personally, sneakers are irritating .. especially when you are in a good long battle.
But by all means, play it anyway you want .. I will just give special attention to the sneaker when I next see them as a red.
