There is a word for "love" in dutch; it's the noun "liefde" (of which lieve is an adjective). However you cannot use "liefde" as a verb, hence my question if this is the case in Deitsch as they are related languages within the Germanic language family.
Usually in dutch we use "houden van" -> To hold (dearly).
But with our grammar the word "houden" may also literally mean to hold. "Ik hou een hamer vast (in mijn hand)." -> "I hold a hammer (fastened in my hand)". In dutch this is considered a different word though, as vast + houden even when written apart in a sentence is considered a compound verb vasthouden. (Like how babysitting in English is not the same verb as sitting).
In German you use the word Lieben as a verb and a noun, so in German you can say Ich liebe dich (I love you) but also like a noun "Die Liebe" (lit: the love)
In Dutch you cannot say: Ik liefde jou, in the same way in English you cannot say: I feelings you.
But you can if use the word Liefde as a noun or adjective to make it something like: - Mijn liefde is alleen voor jou. (lit: My love is only for you). (romantic) - Jij bent mijn ware liefde (lit: You are my true love). (romantic) - Mijn lieve vriend (lit: My lovely friend) (platonic or romantic) - Onze lieve vrouw (lit: Our lovely lady) (exclusively used in reference to Maria AFAIK) - Dat was lief van hem (lit: That was lovely of him). (platonic)
In contemporary Dutch, people use a lot of code switching with English words, so you could hear someone say "love you" romantically, or even just the word "love" mixed in dutch like this:
- Love you, schat (I love you honey) (lit: Love you, treasure) - Ik ben in love (I am in love)
Language purist and language prescriptive Dutch teachers do not like this and would not consider it to be correct dutch. (Which personally I think is absolutely hilarious, as dutch to me is very much a "bastard language" and the notion that we should cling prescriptively to the current version of our language as some sort of canonical form is absurd).
But that's also why I was wondering if _that_ is why the author in the original article was using Liebe instead of Liewe, as code switching with a cognate might allow the loanword to be used as a "verb" while the original word cannot be as it is in contemporary dutch with Liefde/Love. (And I doubt the author would not be aware that Liebe could become something like Liewe in Deitsch as the B in standard high German words when near the end of a word often shifts in dialects and related languages).
