On the contrary, it's something of a scandal they're not transparent about who wrote what, as Google alone spent on the order of $100M in lobbying to shape, and has been all over this for a while. This, from 2020:
“Google, Facebook, and Microsoft are among the companies making huge efforts to shape the upcoming Commission proposals to regulate the digital market. In spite of a new lockdown, the Brussels Bubble is back in action at full speed, with a flurry of online lobby meetings and debates plus highly questionable research papers.” ...
“Who has been lobbying?”
“The quick and simple answer is Big Tech firms, with Google leading the pack.”
”This is clear from the lobby meetings proactively disclosed by the upper echelons of the Commission (commissioners, their cabinets, and directors-general). Since the start of the Von der Leyen Commission, 158 meetings were logged as including discussions on the DMA or DSA Sidenote.”
“These meetings involved 103 organisations, mostly companies and lobby groups. Only 13 actors had at least 3 or more meetings logged on these issues. Google stands out with the most meetings with Microsoft and Facebook trailing close behind. Apple and Amazon have also lobbied on the DMA and/ or DSA, although they rank lower overall with two and one meeting respectively.”
That was 4 years ago. If you think they stopped lobbying, meeting, and writing... then you haven't been paying attention to which EU commissioners are getting kicked out for what and why.
The bill is fine. Apple will lose. It just takes some time.
