Migrating to another cosmos ecosystem will only make many projects forgotten unless web pages are well structures, easy to use and have something good to offer.
If instead of building so many ecosystems, all those developers unite then they could create something much larger than Terra.
As beautiful and easy to use as the Terra Station, anchor, kujira, loop, etc
If Terra disappears I do not think that I will invest in another system of cosmos. Just seeing the interface of those websites make me close and keep me away from them.
The future is terra and not some arid planet that few people use
