Have insurance changes and cancellations hurt the hobby?

If this has been discussed before, i apologize. Recently during pillow talk with a provider, she mentioned that her business has really fallen off in the past two months. She also has had very few requests for references from other providers. Are the cancellations and changes (increases in premiums, deductibles and co-pays) causing hobbiests to sit on their wallets until they know how everything is going to shake out?
