Cuz what you're describing isn't a bitcoin transaction, its data storage. Bitcoin is for Bitcoin transactions. If you want to upload your jpegs to the cloud, go to any of the plethora of failed shitcoins that are happy to help you. Meanwhile I'm going to run a node with filters.

Bitcoin transactions, are made of data. Stored forever. Who cares if someone adds more text or a photo. Leave people alone. It's their bitcoin. They can do w/e they want with it the same way you can choose to not fuck with their transactions. Stop crying people are using their freedom to do things you don't like or agree with. Use your freedom to do the opposite. Bitching solves nothing.
