A EULA is not a binding contract or a license but a means of conveyance as a statement as to what would be considered a violation of their copyrights relating to the redistribution of what they consider to be their property under copyright law as written and will sue for damages.
It’s a “keep off the grass” sign that has little or no impact as to what you do with works in hand as a first purchaser and is of little concern as to personal usage until such works is redistributed. It does not matter if it’s commercial or non-commercial as the mandate and reason for Copyright is to ensure that the holder has the rights to distribution as they see fit regardless of how you make use of assets “in hand” that excludes the intent to redistribute.
Keep it to yourself not a problem until you share their works with thousands of others that they don’t profit from in an uncontrollable manner.
Just to add.
What you can or can not do in an open forum is a moral argument at best, and since I’m not a lawyer, not the ideal place for legal advice as to due diligence.
