As in all other negotiations everything is possible if you have leverage. Unless this union signs the big names then it is doomed to failure.
Now lets take a look at the demands itself:
- Renegotiation of the 32% Google-tax on applications sales:
So you offer google to lose money in exchange for what? Unless you could cause google a lot of pain or show that this can increase total revenue very unlikely to happen.
- Remedy to the Order of Entry Effect
This is core modification of a way the market works. And from a customer view it will not improve my experience. If I search for something, having something mature and tested on top is nice. This is the way current search engines work.
Better solution - try to improve the promotion of new products outside of market.
And every app submitted to the market will also be public right?
- Increased Payment Options
Once again G loses revenue in exchange for ?
- Codified Rules and a Removal Appeal Process
This is reasonable demand. Having such a process will benefit customers at the end - the less developers are worried about this stuff the more they will be able to create applications. Plausible.
- Communication and Engineering Liaison
This is also good idea. If it leads to faster improvement of marker everybody wins.
This can be translated as "Please let me game the system". Very unlikely.
So concentrate on points 5 and 6 for the time being. And if android developer really unite, wouldn't it be a better solution to create a distribution platform that really suits your needs? Now competitive and aggressive platform loved by the customers and developers can just about give you the leverage you need .
