Put and end to expansion by acquisition
The global economy is infested by ever expanding corporate conglomerates. Conglomerates, per se, are inimical to market-capitalism as it was once understood. Conglomeration diminishes competition and leads toward monopoly and/or monopsony powers.
Expansion by managed growth of market share is fine so long as it's not permitted to go too far. Similarly, branching out into another market closely related to that from which a business started (i.e. from a core of expertise, motivation, and experience) need not be detrimental to an overall competitive market. However, expansion by acquisition of solvent companies which in other circumstances could be competitors is wholly against the spirit of market-capitalism.
Apart from the Google instance mentioned here another recent example was Coca Cola acquiring the successful UK Costa Coffee chain. Setting aside aesthetic considerations and worries over whether the Coca Cola Corporation is fit to vend any sort of beverage, that take-over leaves a nasty taste.
Google's starting point was Internet advertising and required developing considerable expertise in computer technology. Google's main business modality remains thus and has been enhanced, from Google's point of view, by widespread take-up of Google's pseudo-open-source Linux variant by phone manufacturers. Google's implementation of Android is a privacy-sapping marketing tool sitting on devices that happen also to enable phone calls.
Google, seemingly, wants to expand into the health information business. That may or may not make sense from Google's point of view. Yet, societal interest is firmly that Google must do so by legitimate competitive expansion rather than acquisition.
Conglomeration and/or global near-monopoly are evils in their own right. They are evident in the likes of Microsoft, Facebook, Twitter, and Amazon. Moreover, distributors of broader cultural output in news, film, TV shows, and music, increasingly are conglomerates of erstwhile production and distribution companies. In the field of physical products, Bayer, now proud owner of the can of legal worms once known as Monsanto, is a conglomerate of monstrous, and dangerously so, proportions.
The root motivator for all this is Ayn Rand compatible neo-liberalism. Consequent globalisation has enabled multinational corporate interests to, in effect, dictate their own terms to nation states. Bribes and promises via lobbyists to members of legislatures and governments aid this continuing process. Little do the corrupted, those accepting such boons, realise their true position as inconsequential nobodies in the grand schemes of others; neither they nor their families shall have a special place within neo-feudalism.
Google's position in the UK NHS may have been promoted, at least welcomed, by dark interests in, or associated with, government, these intent on furthering neo-liberal intentions of privatisation now made more likely by Brexit.
