You are right, the pricing models are hard to compare 1:1. However, most Flixbus' customers can't afford (or don't want to afford) a Bahncard 50 and are very price sensitive. I've been travelling with Flixbus throughout Europe and the crowd is typically either very young or comes from the low-income strata of society. Anecdote ain't data, but that's what I also hear from the folks working there. Also, it has cost DB €10 billion to build the new connection, so they'll have to recoup that investment. Imho and as mschuster91 indicated, they will mainly steal customers from airlines.
