As always, there is no problem untill a team jumps in front of another. They've done one qualifying session, not even a race.
Force India's Szafnauer suggests F1 address 'cloning' à la Haas

I find it disappointing to hear these comments from Szafnauer. Force India themselves get a great deal of components from Mercedes. Also it is well defined within the rules what can be shared and what not. Haas hires Dallara to build them a chassis so it's certainly not the same as the Ferrari. Also, the similarities are with last years Ferrari so it's not even a "current copy". Szafnauer and his team should stop complaining and work harder - or smarter. Nothing stoping them from adopting a similar approach, if Mercedes is up for it.
No doubt if and when Red Bull and Toro Rosso share the same engine in the future, they'll apply a similar approach too.
