Staking has many purposes both in technical (built-in support for native coins, PoS based mining), liquidity (usually on defi tokens and memes), and more. It just depends on what the coin itself or other companies offer. This difference in objectives will usually produce varied views in terms of religious law.
Of course you can't draw any conclusions and use them as a basis for decisions except it's based on an agreement on religious law recognized by competent experts (valid sources are needed).
And as I pointed out above, which most Muslims very conveniently ignore, is the intent. Everything in Islam is about intent and generally, when you are wondering or having an issue about halal/haram (permitted and forbidden), it all boils down to intent (niyat).
And if you are truly religious then only you know your true intent.
