I'm afraid I don't feel like reading through the multiple pages of your response to get all of the details, so I'll just reply with some highlights for now: Regarding the two notifications above, requiring a FUR to allow any non-free image use is not the same as allowing any use of images so long as FURs are provided. That is only one point of WP:NFCC. Free images can be used in ways that non-free images can notso if an image is incorrectly labeled as free its usage may need to be reduced (or it deleted entirely) once it is deemed to be non-free. Trademarks are largely irrelevant for how we use images on Wikipedia, copyright is all that matters, and so simple 'V' designs and the like which are not copyrightable (i.e., they do not meet the threshold of creativity) are not an issue. Some of the football kit logos are too small/obscured to matter (i.e. de minimis), and others such as File:Adidas Logo.svg are too simple). Some of them, however, might very well be too complex to qualify as 'free' and should be deleted from Commons and reuploaded locally for limited use as non-free content. With regards to varying standards by modsas I said above, if there has been actual previous discussion, please point it out to me. Templated notifications about straightforward and obvious failures to meet some of the WP:NFCC requirements are not a conversation. If it is simply a matter of some rules not being enforced consistently, please see WP:OSE.  

 :Again, these are just some things that stood out to me, so please do not take it as a comprehensive reply.
