I ran into the same problem a couple of months ago when a free script ruined the look of the site with ads. I started looking for a clean alternative among well-known meteorological platforms. On the advice of a colleague, I installed the https://billing.meteoprog.com/ marker, having previously checked the structure of the output code. There are no left-hand scripts or ad blocks there. I monitor his work regularly, everything is fair and without unpleasant surprises.
