The question that arises is: based on everything we know about Satoshi and his Bitcoin White Paper, what did he think of these Ordinals? Would he support it, or not?
Since Bitcoin is not centralized and Satoshi doesn't own the right to Bitcoin protocol, technically what he thinks should not matter.
However, Satoshi has always been clear about the purpose of Bitcoin. The reason why he created it. Which is to be a
payment system and it is clear that he didn't want to create a cloud storage. You can see that all over the whitepaper and in his posts in this forum.
Interestingly enough a similar situation rose back in 2010 when people were trying to use bitcoin blockchain to store "arbitrary data" to be used for the project called BitDNS. His opinion about it is clear as he states that it should be
separate and not in bitcoin blockchain. That is why a separate project called Namecoin was created.
