https://www.bitfinex.com/posts/466From a business point of view, I find legitimate to remove underperforming coins/pairs. Bitfinex isn't the first and not the last to do it, as they say, it will help to consolidate and improve liquidity. It still one of the top exchange platforms by volumes.
They also delisted ~50 trading pairs 2 weeks ago for the same reason of low liquidity, look like Bitfinex is in a serious spring cleaning period.
"increasing competition within the altcoin space," considering 99% of altcoins are useless, even if it was bananas it would be the same
it is also a big help in the market removing those useless coins /tokens can help to trader's determine what will be good coins to choose to invest. There are many choices already and removing those low liquidity coins can help also to increase the volume of other coins thats not belong to the coins that will not delist.
Hope other exchange will also do the same we have many shit coins now in tha market and having many coins is not really help the market to grow.
