Sage 200 Manufacturing- withdrawal of support

We have been advised today 4/11/2020 that you are withdrawing Sage 200 Manufacturing as of 1/11/2020 from sale and that it will no longer be supported from next year or later, depending on which version is in place. Instead we can migrate to Sicon Manufacturing for a fee, albeit less 20% if we do it soon. Weare a manufacturing business and migrated from Sage 50 Accounts Manufacturing to Sage 200cin 2019 because we were sold the idea that Sage 200c is an all in one package that is future proof, and obviously because it was very similar to Sage 50 (!) and that everything would migrate across seamlessly (!!). Why do you appear to be abandoning Manufacturing as a supported service? How reliable will the Sicon add-on be and will it genuinely seamlessly integrate with the core module or will we end up witha re-run of the clunky Sage 50 Manufacturing module that you also abandoned support on? Whydoes Sage have to rely on bought in add-ons to make their core softwarebetter or indeed useable, in this case for manufacturing businesses? Should we be looking to move to a non-Sage platform?
