Sorry for the double reply, but another useful perspective in this is derogation. I often forget this idea because I'm very class minded, but it's also very important. This is the idea that a culture can be profited off of while simultaneously despising the people that practice it. In practice, this exists as a business around a specific cultural item succeeding specifically because the business is NOT owned/operated by the original cultural group. Some of the best examples of this are around Black American culture in the US. Some cultural products were only valuable AFTER they were owned, operated, and proliferated by White Americans. Which is kinda just Racism Classic™ but allowing certain useful things to cross the cultural line for profits sake.

The know of cultural ownership is absolutely unravel-able in many situations, just not all. In some situations it's exceedingly clear and in others, not. I think you're trying very hard to find hard-and-fast, absolute rules for these situations, but they don't exist. The keyword is nuance, nuance, nuance. Each situation is different and each situation deserves scrutiny as to whether or not it crosses the line. This is a judgement call made by each and every person.

If you really want me to engage on the specific situation of Tostitos/chips and salsa I will, so you can see the process of my scrutiny.

First, I think that as any item of culture becomes more and more diffused (ethically or not), it's original ownership becomes diluted. Things that were once appropriation in the distant past, if done today, would not be considered as such as the context around them changes (in a myriad of ways).

So, if Tostitos started as a company today, I'd say making chips and salsa is not appropriation. But, if Tostitos was founded a long time ago, before chips and salsa were a foodstuff ubiquitous across the US and Tostitos was created by one outside of that cultural ownership, then I'd say it likely was appropriation. It also might be fair to argue that in the modern day for Tostitos specifically, "the damage has been done" and there really isn't much fixing it, so consuming their products isn't necessarily problematic. But this would be a point as to why identifying appropriation early on and stopping it is especially important.

As to whether I'm part the problem - for Tostitos no, but for other things almost certainly yes. I'm human and I don't know everything, and I've certainly made mistakes in this area, but that's okay. What's important is that once I've learned something is in fact a mistake, I own up to it and stop making that mistake.
