No, it wouldn't have been, as the DMA only applies to 'gatekeepers' and if you're new, you're simply not a gatekeeper. You need at least 45 million monthly active users and 7,5 billion of revenue for three years.

> So EU should change Apple’s and Google’s status from producer to provider of essential service like electricity for example.

That's the whole point of the DMA: designate these parties as 'gatekeepers', providing essential services ('core platform services' in terms of the DMA). Once you are, you have certain obligations that should allow proper interoperability with other/smaller parties.
