For now it is relatively easy just not to buy the product. I have no idea why people buy super-expensive light bulbs that or thermostats that you can't control if the wifi goes down or the company behind them goes bust. Most "internet of things" gadgets right now are expensive rubbish. But data-mining corporations are not stupid and I expect these things will be pushed on us harder and harder until there is no alternative but to let them into your home. We accept the privacy compromises associated with smartphones because you can't buy a privacy-protecting phone; soon this may be the case with washing machines and toasters. I hope people laugh this stuff out of the market but... my colleague just spent $200 on 3 light bulbs that spy on him, and he can't see what's absurd about that.
