Do costs of products increase as a consequence of the reviews of the MRIS? We are convinced about this

We wrote some reviews about Krisztián Hofstädters OpenBCI EEG setup with the Greentek Gelfree S3 EEG cap and some reviews about Richard Davidsons studies with long-term meditators:

Shortly after that Krisztián Hofstädters OpenBCI demos disappeared from his YouTube channel. And instead of that the Unicorn Black by g.tec medical came on the market, which is as a total more expensive than OpenBCI, due to the costs of the Python API which is not free.

Also Krisztián Hofstädters Greentek Gelfree S3 disappeared from his YouTube channel. But then Greentek Gelfree S3 demos appeared on the YouTube channel of mbrainTrain, which are devices which are more expensive then OpenBCI.

Has this shift to more expensive EEG devices where promoted after our reviews something to do with the long-term reviews in our journal? We are convinced about this.
