I posted a while ago about an update to the Soapbox OS section of the main website:- this was about the fiasco regarding the license required to display a segment of OS mapping on a walking website (over and above the 10 segments you get free via GetAMap). To recap, the Paper Map Copying License (PMCL) was required, as per the question in their own FAQ, and it had to be a copy of a paper map:- there was no license at all that allowed the display of maps from digital mapping software.
It now appears that the lumbering OS behemoth has been stirred into action: they are conducting an internal review of the PMCL terms, which we assume is primarily to close what they see as a loophole - a generous interpretation of the license wording. This will very likely mean the end of the simple PMCL option costing 47.50 + VAT per year for displaying routes.

The terms of the PMCL will almost certainly be reworded so that they exclude displaying the copy on a website. If no other changes are made to the licensing structure, there will be no consumer affordable way at all for walkers to show their routes on OS mapping, and their existing website maps will have to be removed. The only alternative at present is an Internet License which would be vastly more expensive.
