It is a quite good movement of the google that they are trying to remove some extension relayed to their corporation that is not legit and authentic today there are a lot of people now are supporting the use of the bitcoin and to encourage them to make more support they need to retain only the cryptocurrency that is really paying some attention to their users and customers because this is the reason why the users want to use those extension and because of earning if they didnt get any payment on these platform they will not trust the platform again and the cryptocurrencu and may cause of spreading the news rapidly that has impact to their earnings too.
yes you are right about the company's revenue which is caused by extension services that are constantly being improved.
As a crypto user it must be vigilant in choosing extensions. Security that is always prioritized by the developer of the extension will be in demand by many people. Maybe you know about the Metamask extension that was detected as phishing which stole the user's private key data. That is an illegal Metamask Extension and not from an Official Metamask. The incident was successfully controlled by Metamask directly and the Extension can be removed so that there are no more victims.
