Manufacturers are NOT INTERESTED in selling low-cost dumb TVs when they can sell smart TVs and get long-term returns. They are even willing to sell the TVs at cost because they will monetise later with ads and selling your data.
Manufacturers don’t want you to have a dumb TV, they want everyone to go smart - which is part of why business-targetted dumb panels are priced higher - to disincentivise regular end-customers from buying.
