Business Integration of LLMs in the Face of Privacy Concerns

It's obvious that one of the biggest hurdles in the commercial adoption of LLMs is and will continue to be in the short term privacy concerns around data, whether that be proprietary information around industry knowledge or heavily regulated domains like health or finance. Are any of you seeing this start to shift or see these concerns be dealt with? Of course some of the massive corporations likely have the infrastructure to deal with this, but for many it's likely not feasible currently.

Any insight you could provide here would be helpful/interesting. As things stand, even if we had models that were far more capable than the current set, it seems we still have a long way to go in terms of adoption and integration. This isn't meant to be inflammatory and I'm not requesting specifics on company names or details on the process, just looking to get a sense of whether the winds are changing.
