No, it is the cost of free. For the most part it is reporting fact (this could happen), but used to promote other Avast paid products to prevent it.
I have been using Avast Free for over 17 years and I don't find the volume excessive, perhaps I have a higher tolerance and possibly don't get as many as new users might (it seems to slow down).
Some I just have a laugh at, some I just thing so what, I know my IP is visible (if I was concerned I would use a free VPN that they are trying to sell me), but I'm not unduly concerned.
I recently tried a free VPN for just over a week, but I have since uninstalled it.
