Yes it could be. actually they want to adopt blockchain technology, but they do not want to be able to compete, facebook also intends to make their own coins, and the coins are determined to beat bitcoin.

A lot of Internet companies banned crypto/ICO ads, Google, Twitter, Facebook, LinkedIn, Snapchat, Microsoft, Baidu, MailChimp, Oath, Alibaba’s Taobao, Yandex etc, guess what, they are all planning to launch their own cryptocurrency, is it Quite a possibility, but for the time being it has more to do with no solid crypto regulatory guidelines, with all the scam ICO advertising targeting innocent investors, these companies are just taking a precaution to not get dragged into any legal implications.

In market there is many coins available but Bitcoin is ruling the crypto market nowadays and based on this many companies can see the profit of crypto currency so facebook banned btc advertisement and they wants to buildup their own coin but it’s not going to profitable for them because already btc captured the market and many people and govt. using this currency.

If it's anything to go by then it's a good move. At least it will be much more easier to make payments on their platform. Bitcoin technology is the future.

I'm not sure they will do that due to no confirmation from them.
And also the rumors that facebook will create a cryptocurrency is also not confirmed yet, it's still a rumour.
So, it could be many big corporate starts crypto era in the future or even they leave cryptos, who knows.

Hi there CryptoRaymond! I suppose they wont. Those are the most common misconception about blockchain. When a certain company have announce that they are exploring the blockchain system, most of the people will then think of an ICO is on its way. Sooner, that company will offer airdrops of their coin and do some further advertisement to attract more investors. But the blockchain could be use in many things not just in the digital currency. Its open ledger and decentralize approach could help those search engine to deliver the user requested content in a more faster way.

as i heard about facebook, they are planning to make their own coins if i am not wrong b ut i have no clue about bing right now. eventually everyone has to come to wards cryptos, it is the future.

Bing with crypto? it's like Kodak's crypto announcement?
all these big old companies, are in my opinion, just trying to get some market boost by talking about crypto.
not necessarily because it's actually relevant to have their new products or utilization by crypto.
they're scared! 

If this is true, then the reason behind banning crypto os because they want to make their own crypto.
But i think slow or fast, every companies will use crypto in the future

This is not a new thing, some websites first also have news like this, speculation from every news also popping up one of them as you say, could happen
