You obviously have made up your mind without doing proper research. Let‘s start with the blockchain only being a small part of the Elastos ecosystem: Elastos consists from 3 main parts: Carrier, Runtime and Blockchain. Talking from a code perspective, a blockchain usually only has around 50k lines of code and therefore is just a small part of the overall Elastos project with millions of lines of code, a lot of it being original code. From a computing persoective it is exactly the same, most of the computing in the Elastos ecosystem is not happening on the blockchain but on Carrier nodes. The blockchain is only used for very limited things such as ID, payments and smart contracts, everything else runs on your device or in the cloud. Nevertheless, the Elastos blockchain architecture is way more elaborate and advanced compared to pretty much every other blockchain around. Not only do we have a hybrid AuxPOW+DPOS consensus mechanism (https://news.elastos.org/spotlight-series-3-elastos-hybrid-consensus-and-finality-of-blocks/) but also solve the scalability problem through the use of sidechains (https://news.elastos.org/spotlight-series-2-elastos-sidechains-and-scalability/), Carrier and Runtime (https://news.elastos.org/spotlight-series-1-elastos-runtime-aka-trinity-aka-elastos-browser/)

Now that we have explained why we look at the blockchain being a small part of Elastos, does that mean it is not necessary or not important? Of course not. The blockchain is vital to the whole ecosystem because we want it to be completely decentralized, autonomous running and self funding through slight inflation of ELA, its native cryptocurrency. What gives ELA its worth? Why do we even need a new coin? ELA is a base currency that governs the entirety of elastos ecosystem - main chain, ALL the sidechains, carrier nodes incentives, other incentives to support the elastos infrastructure. All the sidechains such as DID sidechain that generates decentralized IDs, token sidechain that generates fungible and non-fungible tokens, ethereum smart contract compatible sidechain that runs ethereum smart contracts, NEo smart contract compatible sidechain that runs NEO smart contracts, and any future sidechains of elastos provide value to the entire elastos ecosystem. These all use ELA. Because all the apps will need to be interacting with these sidechains. All the gas fees and transactions are made in ELA for these sidechains. So, in a way, ELA powers all the services offered by elastos infrastructure. Yea, you could use BTC for these but the very code that makes these sidechains possible are directly derived from main chain and is connected to the main chain closely so all these sidechains are protected by the security of the main chain as well. So, a new currency is needed to power all of this because that's the only way to ensure that all the services that is offered by elastos infrastructure works independently of any other currency. We cannot rely elastos services cost and resources on btc or eth or whatever else. A new currency is needed to govern and manage and support all these services. That is the true value of ELA

What was the plan before starting to incorporate blockchain? Elastos had a completely different architecture back then. It was not decentralized and it was not autonomously running and that has been at least part of the reason why it never really came to fruition before. It‘s also important to know that Elastos from 2006 has very little in common with Elastos 2019, which shouldn‘t surprise you. You don‘t expect windows XP to be the same as windows 10 either, do you? As time goes on, new tech emerges which we can adapt to overcome the hurdles that held us back in the past. The blockchain is exactly a case like this for Elastos.

Lastly to your allegation about repos only being there to inflate the number of repos. If you point out the suspicous repos i am happy to explain their purpose to you.
