First of all I'm afraid that DNG will slow down the progress in the
raw converters. Now we have a situation where they need to add
support for new cameras and while they're at it they fix other
things. Being fast with adding new cameras is a competitive edge, and
I want them to compete fiercly.

Then you misunderstand what having a native DNG format would offer. If a camera shot a DNG format, and a raw converter supported DNG, then the raw converter would support a new camera that shot DNG without any work on the part of the raw converter. Ya see, that's the purpose of a standardized raw file format...less of the drama about new camera support.

Second, adding a new step in the workflow costs money, and there's
nothing that suggests that DNG files will be more future-safe than
native formats.

Yes, one thing...DNG is fully documented where as the proprietary raw file formats are not. In terms of archive standards, that's like the difference between nite and day. The fact that DNG is open and fully documented means that long term conservation and preservation is MUCH more likely. The other main factor in conservation is that the more supported a file format is, the greater likelihood that format will survive. At the moment, DNG supports over 200 DIFFERENT raw file formats. As new cameras come along the new file formats propagate like rabbits.

If the digital photo industry started adopting a standardized raw file format that was documented, then long term conservation and preservation would be greatly enhanced. With more an more new undocumented formats coming along, the likelihood that future support will be eliminated grows–so the more undocumented formats, the greater the risk to the industry.

Now, native raw files in the camera will not be as good as the native
ones, simply because that will hurt the major manufacturers. So
they'll cripple the DNG versions some. They have to.

No, they don't. You really don't understand raw file formats if you think this. Current CR2 and NEF raw file formats, based on TIFF-EP (the ISO "standard") are already so close to being DNG that the camera makers would lose nothing by taking their raw data and putting it into a DNG wrapper instead of the undocumented, proprietary wrapper. DNG supports private maker notes that can contain proprietary metadata so if there was "secret sauce" it can be saved as such. The camera makers would not loose anything by adopting DNG with the possible exception of being free to create technically poor formats.

Last, and this one I'm not that proud of ...
I hate petitions in forums, especially if they are off topic to begin

If you are a digital photographer, then the topic of undocumented and proprietary raw file formats is indeed on topic. There is NOTHING in the current situation of hundreds of undocumented, proprietary raw file formats that is the least bit good for photographers. The current situation simply sucks for everybody except for the camera makers. Having built-in DNG support in new cameras would benefit everybody (and actually benefit the camera makers as well) because new cameras would have built in compatibility with existing software.

In fact, DNG cameras would actually HELP the raw processing community because individual raw processors would not need to decode each and every format and allow small specialty companies to compete against Adobe and Camera Raw easier. Even Nikon and Canon software could process each other's raw files. Adopting DNG would actually HELP those people who seem predisposed to hate Adobe because it would provide opportunities to use NON-Adobe software.

If you are a photographer, it would behoove you to actually know and understand what the issues are. The industry, as it stands today is NOT in the best interests of photographers...a standardized and fully documented raw file format is–regardless of what you may think of Adobe.
