Some dApps will be fine with constant requests for key authorizations, spending your Ether on gas fees. Others will undoubtedly run better on a blockchain with zero transaction fees (like EOS 😉). Given Ethereum's (relatively) long history, I can understand how/why many projects were/are being launched on Ethereum/EVM.

Developers now have the ability to do MVPs or PoCs or even beta test their dApps on their more "familiar" platform, and then easily migrate to EOS for final release/scale/etc. Kind of like how Docker enables devs to build "locally," and later have that same container installed in production.

This is why I love the EOS ecosystem so: it is all community-driven, and the community knows what the community wants and needs (with members incentivized to work together via BP elections, further driving development of high-quality software for EOS) with the end result being a platform that has matured quickly and continues to improve by the day — thanks in no small part to groups like shEOS! 👩‍💻👏
