As long as the firmware is proprietary and cannot be inspected or modified, the only reliable way to avoid snooping by tech industry is not to connect any "smart" device to the Internet. Use the TV as a dumb monitor for a PC under your control (running Linux). If streaming service X will not run on Linux because DRM is not implemented or enforceable on a free device, do without it, or find alternative sources for the content (hint: Linux ISOs).
